Our objective was to determine if otherwise healthy children age ≥3 years with an apnea-hypopnea index (AHI)<24 on overnight PSG can be safely discharged on the same day of surgery. Case series with chart review of children age <18 years with positive PSG (AHI>2) who underwent adenotonsillectomy (T&A) between January 2013 and August 2019. Data collected included patient demographics, medical history, comorbidities, PSG results, operative details, length of stay, intraoperative and postoperative respiratory complications and management. Potential predictors of respiratory complications were evaluated using chi-square/Fisher's exact test and 2-tailed unpaired t tests with the Bonferroni adjustment for multiple comparison artifact. The percentages of healthy children age ≥3 ypredictive of postoperative complications with an AHI ≥10 but <24, 113 (68.5%) were discharged home on the same day of surgery without additional respiratory sequelae. This study demonstrates a low risk of respiratory complications after T&A. Otherwise healthy children age ≥3 years with AHI <24 may be considered for ambulatory discharge. This study demonstrates a low risk of respiratory complications after T&A. Otherwise healthy children age ≥3 years with AHI less then 24 may be considered for ambulatory discharge.The EU goal to reduce marine plastic litter by ca. 30% by 2020 stressed the need to deploy analytical methods to ascertain the polymeric nature of a residue. Furthermore, as plastics age under natural conditions and usual databases do not include their weathered spectra, (micro)plastics in environmental samples may be unidentified. In this paper, polyamide (nylon) microplastics weathering was monitored because of its u
